Description

Technical Field

[0001] This invention relates to the field of vibrating screen device technology, and more particularly to a vibrating screen device for titanium dioxide production. Background Technology

[0002] In titanium dioxide production, ultrasonic vibrating screens are key equipment for solving the problem of fine sieving, especially suitable for high-mesh sieving requirements. Because the particle size distribution of finished titanium dioxide needs to be strictly controlled according to different application scenarios (such as 40-325 mesh in the coatings and plastics industries), ultrasonic vibrating screens are an irreplaceable core sieving equipment in titanium dioxide production. Furthermore, ultrasonic vibrating screens need to effectively separate ultrafine particles through high-frequency vibration to ensure particle size uniformity.

[0003] It should be noted that existing ultrasonic vibrating screens simply add titanium dioxide through the feed hopper during the screening process. This continuous, large-volume feeding causes constant impact on the upper screen, making it highly susceptible to damage. Furthermore, if the titanium dioxide becomes excessively damp during production due to improper storage or other unforeseen circumstances, it can clump or form lumps that directly enter the ultrasonic vibrating screen, also causing damage. Since the damage is in powder form, it is difficult for workers to detect, resulting in substandard titanium dioxide screening quality. Summary of the Invention

[0004] The purpose of this invention is to provide a vibrating screen device for titanium dioxide production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0027] A support spring is installed on the bottom inner wall of the pressing groove, and the top of the support spring is installed on the pressing drive frame.

[0028] The beneficial effects of the vibrating screen device for titanium dioxide production proposed in this invention are:

[0029] In this invention, by setting up a rotary feeding mechanism, when screening titanium dioxide using a vibrating screen, multiple vibrating screen cylinders are used in combination. The drive motor drives the rotating material column to rotate, and drives the feeding hopper to rotate. The rotation of the feeding hopper drives three intermediate feeding pipes to rotate. When the intermediate feeding pipes rotate, they coincide with the outer pull-off plate, allowing titanium dioxide to enter the feeding hood through the connecting holes on the outer pull-off plate, achieving the purpose of intermittent feeding and avoiding the problem of excessive feeding damaging the screen. At the same time, during the rotation of the intermediate feeding pipes, three rotating stirring frames are driven to rotate simultaneously. The three rotating stirring frames drive three unblocking gears to rotate on the drive gear ring, thereby driving the three rotating stirring frames to rotate synchronously, unblocking the titanium dioxide in the intermediate feeding pipes, avoiding the problem of feeding failure or feeding agglomeration due to titanium dioxide agglomeration, and solving the problem of continuous operation of ultrasonic vibrating screens in the screening of high-viscosity powders.

[0030] Furthermore, in this invention, by setting up an emergency material cut-off mechanism, when titanium dioxide falls onto the feed transfer plate, the impact force of the titanium dioxide can be effectively reduced, avoiding the problem of excessive impact force damaging the screen of the vibrating screen cylinder. Moreover, if the titanium dioxide is too wet, it will stick to the feed transfer plate, thereby driving the feed pull-down bracket to move, or the screen inside the vibrating screen cylinder will be damaged, causing a large amount of material to be discharged from the discharge pipe. Similarly, titanium dioxide will quickly accumulate on the discharge transfer plate at the corresponding position, which will then cause the discharge transfer plate to drive the discharge pull-down bracket to move, and the discharge pull-down bracket to drive the feed pull-down bracket to move. This will cause the outer material cut-off plate to block the transfer feed pipe, preventing a large amount of wet material from falling into the vibrating screen cylinder and causing damage to its internal screen, or preventing the vibrating screen cylinder from being damaged but still running, thus preventing the titanium dioxide from being fully screened.

[0031] Furthermore, in this invention, by setting up an over-vibration separation mechanism, when the vibrating screen cylinder vibrates abnormally, the vibrating screen cylinder causes the pressing drive frame to move. The pressing drive frame moves vertically within the pressing groove, causing the support spring to contract under force. When the pressing drive frame moves, it simultaneously drives the wedge-shaped separation block. The wedge-shaped separation block presses the centralized separation plate to move. The centralized separation plate slides on one side of the control box through the limiting pull rod, thereby causing the centralized separation plate to simultaneously drive the three plugs to separate from the control box, thus achieving the purpose of active separation and avoiding the problem that the vibrating screen cylinder continues to vibrate during excessive vibration, causing further damage to the vibrating screen cylinder.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0049] Please refer to the attached instruction manual. Figures 1-10 The present invention provides a vibrating screen device for titanium dioxide production, which includes at least three vibrating screen cylinders 1, a main support 4 installed on the three vibrating screen cylinders 1, a vibrating base 3 connected to the bottom side of the vibrating screen cylinder 1, three control boxes 8 installed on the main support 4, three plugs 10 plugged into one side of the control box 8, a vibrating cable 9 connected to the plug 10, the vibrating cable 9 connected to the vibrating screen cylinder 1, a feed hopper 5 connected to the three vibrating screen cylinders 1, and three discharge pipes 2 installed on one side of the vibrating screen cylinder 1.

[0050] Furthermore, in this embodiment of the invention, a rotary feeding mechanism 6 is also included. The rotary feeding mechanism 6 is installed on the feeding hopper 5 and is used to feed the three vibrating screen cylinders 1 intermittently. Specifically, the rotary feeding mechanism 6 includes three intermediate feeding pipes 601, which are installed on the feeding hopper 5. A feeding seat 608 is installed on the main support 4, and a drive motor 602 is installed on the feeding seat 608. A rotary material distribution column 603 is installed on the output shaft of the drive motor 602 and is installed on the bottom side of the feeding hopper 5. It should be noted that, in this embodiment of the invention, when the vibrating screen screens titanium dioxide, the drive motor 602 drives the rotating bulk column 603 to rotate, and drives the feed hopper 5 to rotate. The rotation of the feed hopper 5 drives the three intermediate feed pipes 601 to rotate. When the intermediate feed pipes 601 rotate, they overlap with the outer pull-off plate 702, so that the titanium dioxide enters the feed hood 607 through the feed connection hole 703 on the outer pull-off plate 702 to achieve the purpose of intermittent feeding. At the same time, during the rotation of the intermediate feed pipes 601, the three rotating stirring frames 604 are driven to rotate simultaneously. The three rotating stirring frames 604 drive the three unblocking gears 605 to rotate on the drive gear ring 606, thereby driving the three rotating stirring frames 604 to rotate synchronously, unblocking the titanium dioxide in the intermediate feed pipes 601, and avoiding the problem of feeding failure or feeding agglomeration due to titanium dioxide agglomeration.

[0051] Please refer to the instruction manual attached. Figures 4-7 More specifically, the present invention provides a vibrating screen device for titanium dioxide production, wherein an emergency material cutting mechanism 7 is installed on the rotating feeding mechanism 6. The emergency material cutting mechanism 7 is used to cut off the feed of the three vibrating screen cylinders 1 in an emergency. The emergency material cutting mechanism 7 includes three external material cutting plates 702. Three external sliding grooves 701 are opened on the top side of the feeding seat 608. The three external material cutting plates 702 are respectively slidably installed in the three external sliding grooves 701. It should be noted that in this embodiment of the invention, when titanium dioxide falls onto the feed transfer plate 709, if the titanium dioxide is too wet, it will stick to the feed transfer plate 709, causing the feed transfer plate 709 to move downward under force and drive the feed pull-down bracket 708 to move. This damages the screen inside the vibrating screen cylinder 1, causing a large amount of material to be discharged from the discharge pipe 2. Similarly, this causes titanium dioxide to accumulate rapidly on the discharge transfer plate 711 at the corresponding position, causing the discharge transfer plate 711 to drive the discharge pull-down bracket 710 to move. Then, the discharge pull-down bracket 710 drives the feed pull-down bracket 708 to move, which in turn causes the outer pull-off plate 702 to move. The outer pull-off plate 702 blocks the transfer feed pipe 601, preventing a large amount of wet material from falling into the vibrating screen cylinder 1, thereby achieving the purpose of emergency material cut-off and avoiding continuous damage to the inside of the vibrating screen cylinder 1.

[0052] More specifically, in this embodiment of the invention, three vibration separation mechanisms 11 are also included. These three mechanisms are respectively mounted on three control boxes 8. Each vibration separation mechanism 11 is used to separate the plugs 10 from the control boxes 8. Each vibration separation mechanism 11 includes a centralized separation plate 1101, which is movably mounted on one side of the control box 8. All three plugs 10 are engaged with the centralized separation plate 1101. Moving the centralized separation plate 1101 disengages the three plugs 10 from the control box 8. It should be noted that in this embodiment of the invention, when the vibrating screen cylinder 1 experiences abnormal vibration, the vibrating screen cylinder 1 presses down on the driving frame 1104 to move, thereby causing the centralized separation plate 1101 to simultaneously separate the three plugs 10 from the control box 8. This achieves active separation and avoids the problem of the vibrating screen cylinder 1 continuing to vibrate during excessive vibration, which could cause further damage to the vibrating screen cylinder 1.

[0053] Please refer to the instruction manual attached. Figures 2-4 Furthermore, the vibrating screen device for titanium dioxide production provided in this embodiment of the invention includes a rotary feeding mechanism 6 that further includes three rotary stirring frames 604, which are rotatably installed in three intermediate feed pipes 601. In addition, a clearing gear 605 is installed on the top side of the rotary stirring frame 604, and a drive gear ring 606 is installed on the feed seat 608. The clearing gear 605 meshes with the drive gear ring 606. It should be noted that in this embodiment of the invention, the drive motor 602 drives the rotating bulk material column 603 to rotate, and drives the feed hopper 5 to rotate. The rotation of the feed hopper 5 drives the three intermediate feed pipes 601 to rotate. During the rotation of the intermediate feed pipes 601, the three rotating stirring racks 604 rotate simultaneously. The three rotating stirring racks 604 drive the three unblocking gears 605 to rotate on the drive gear ring 606, thereby driving the three rotating stirring racks 604 to rotate synchronously, so as to unblock the titanium dioxide in the intermediate feed pipes 601 and avoid the problem of feeding failure or feeding agglomeration caused by titanium dioxide agglomeration.

[0054] More specifically, in this embodiment of the invention, three feed hoods 607 are installed on the bottom side of the feed seat 608, and the three feed hoods 607 are respectively installed on three vibrating screen cylinders 1; in addition, three feed holes 609 are opened on the feed seat 608, and the three feed holes 609 are respectively located within the range of the three feed hoods 607. It should be noted that, in this embodiment of the invention, titanium dioxide enters the feed hoods 607 through the feed holes 609 on the feed seat 608, and then enters the vibrating screen cylinder 1.

[0055] Please continue to refer to the instruction manual appendix. Figures 4-7Furthermore, the vibrating screen device for titanium dioxide production provided in this embodiment of the invention includes an emergency material cutting mechanism 7 that further includes three external pull brackets 704, which are respectively installed on three external material cutting plates 702.

[0056] In addition, three external pull rods 705 are rotatably mounted on the bottom side of the feed seat 608. A rotating push shaft 707 is mounted on each external pull rod 705, and the rotating push shaft 707 is movably mounted within the external pull frame 704. It should be noted that, in this embodiment of the invention, when the external pull rods 705 rotate, they push the external pull frame 704 to move via the rotating push shaft 707. This causes the external pull frame 704 to move the external pull cutting plate 702, which slides within the external pull groove 701, thus achieving the purpose of actively blocking the transfer feed pipe 601 through the external pull cutting plate 702.

[0057] More specifically, in this embodiment of the invention, the bottom side of the feed seat 608 is provided with three reset rotating slots 719, and a reset rotating shaft 706 is rotatably installed in each of the three reset rotating slots 719. Three external pull brackets 704 are respectively installed on the three reset rotating shafts 706. A reset torsion spring 720 is installed on the reset rotating shaft 706, and the reset torsion spring 720 is installed on the inner wall of the reset rotating slot 719. It should be noted that, in this embodiment of the invention, when the external pull rod 705 rotates, it rotates on the reset rotating shaft 706 and drives the reset torsion spring 720 to be subjected to force. Therefore, the rebound force of the reset torsion spring 720 can help the external pull rod 705 to reset.

[0058] Please continue to refer to the instruction manual appendix. Figures 4-7 More specifically, in this embodiment of the invention, three sliding push plates 712 are slidably installed on the bottom side of the feed seat 608, and the sliding push plates 712 are moved to push the outer pull frame 704 to rotate.

[0059] In addition, each of the three vibrating screen cylinders 1 is equipped with a feed transfer plate 709, and each of the three feed transfer plates 709 is equipped with a feed pull-down bracket 708, which is movably mounted on one side of the sliding push plate 712. It should be noted that, in this embodiment of the invention, when the sliding push plate 712 slides, it pushes the outer pull rod 705 to rotate, causing the outer pull bracket 704 to drive the outer pull cutting plate 702 to move, thereby achieving the purpose of blocking the transfer feed pipe 601 through the outer pull cutting plate 702.

[0060] More specifically, in this embodiment of the invention, a drive sliding shaft 714 is rotatably mounted on one side of the feed pull-down bracket 708, a drive sliding hole 713 is opened on one side of the sliding push plate 712, the drive sliding shaft 714 is slidably mounted in the drive sliding hole 713, and a discharge transfer plate 711 is provided on the bottom side of the three discharge pipes 2 located on the same vibrating screen cylinder 1. A discharge pull-down bracket 710 is mounted on the three discharge transfer plates 711, and the discharge pull-down bracket 710 is mounted on the feed pull-down bracket 708.

[0061] In addition, the bottom side of the feed seat 608 is provided with three pull-down slots 721, and the top sides of the three feed pull-down brackets 708 are slidably installed in the three pull-down slots 721 respectively, and each is equipped with an upper pull spring 722, which is installed on the inner wall of the top side of the pull-down slot 721. It should be noted that in this embodiment of the invention, when titanium dioxide adheres to the feed transfer plate 709, the feed transfer plate 709 is forced to move downward and drives the feed puller 708 to move. Alternatively, if the vibrating screen cylinder 1 is damaged, causing a large amount of material to be discharged from the discharge pipe 2, titanium dioxide will also accumulate rapidly on the discharge transfer plate 711 at the corresponding position. This will cause the discharge transfer plate 711 to drive the discharge puller 710 to move, and the discharge puller 710 to drive the feed puller 708 to move. The feed puller 708 moves vertically downward in the pull groove 721 and causes the pull spring 722 to be stretched. When the feed puller 708 moves, it moves in the drive sliding hole 713 through the drive sliding shaft 714, thereby driving the sliding push plate 712 to slide horizontally, achieving the purpose of automatic material cutting.

[0062] Please continue to refer to the instruction manual appendix. Figures 4-7 More specifically, in this embodiment of the invention, the outer pull-out plate 702 is provided with a feeding communication hole 703, and two positioning slots 717 are provided on both sides of the outer pull-out plate 702; in addition, two positioning spring slots 715 are provided on the inner walls of both sides of the outer pull-out slide 701, a positioning spring 718 is installed on the inner wall of the positioning spring slot 715, and a positioning spring rod 716 is installed on the positioning spring 718, one end of the positioning spring rod 716 is locked in the positioning spring slot 715. It should be noted that, in this embodiment of the invention, when the outer pull-out plate 702 moves, it squeezes the four positioning spring rods 716 to retract simultaneously, so that the positioning spring rods 716 move in the positioning spring slots 715 and drive the positioning springs 718 to contract under force; when the outer pull-out plate 702 moves to the designated position, under the rebound force of the positioning springs 718, the positioning spring rods 716 are driven to lock in the corresponding positioning slots 717, thereby achieving the purpose of positioning the outer pull-out plate 702.

[0063] Further, please refer to the appendix to the instruction manual. Figures 8-10The present invention provides a vibrating screen device for titanium dioxide production. The over-vibration separation mechanism 11 further includes a wedge-shaped separation block 1103. A downward pressure drive frame 1104 is movably mounted on the vibrating base 3. The wedge-shaped separation block 1103 is mounted on the downward pressure drive frame 1104. The downward pressure drive frame 1104 moves down to drive the wedge-shaped separation block 1103 to squeeze the centralized separation plate 1101, which is used to drive the three plugs 10 to disengage from the control box 8 through the centralized separation plate 1101.

[0064] In addition, two limiting rods 1102 are installed on one side of the centralized separation plate 1101, and the two limiting rods 1102 are slidably installed inside the control box 8. It should be noted that, in this embodiment of the invention, when the downward drive frame 1104 moves, it simultaneously drives the wedge-shaped separation block 1103. The wedge-shaped separation block 1103 squeezes the centralized separation plate 1101 to move, and the centralized separation plate 1101 slides on one side of the control box 8 through the limiting rods 1102, thereby causing the centralized separation plate 1101 to simultaneously drive the three plugs 10 to separate from the control box 8, thereby achieving the purpose of active separation.

[0065] More specifically, in this embodiment of the invention, a downward pressure groove 1105 is provided on the vibration base 3, and a downward pressure drive frame 1104 is slidably installed in the downward pressure groove 1105; a support spring 1106 is installed on the bottom inner wall of the downward pressure groove 1105, and the top end of the support spring 1106 is installed on the downward pressure drive frame 1104. It should be noted that, in this embodiment of the invention, when the downward pressure drive frame 1104 moves, it moves vertically within the downward pressure groove 1105, causing the support spring 1106 to contract under force.

[0066] In summary, the working principle of the vibrating screen device for titanium dioxide production provided in this embodiment of the invention is as follows:

[0067] When the vibrating screen screens titanium dioxide, the drive motor 602 drives the rotating bulk column 603 to rotate, and drives the feed hopper 5 to rotate. The rotation of the feed hopper 5 drives the three intermediate feed pipes 601 to rotate. When the intermediate feed pipes 601 rotate, they overlap with the outer pull-off plate 702, so that the titanium dioxide enters the feed hood 607 through the feed connection hole 703 on the outer pull-off plate 702. At the same time, the rotation of the intermediate feed pipes 601 drives the three rotating agitators 604 to rotate simultaneously. The three rotating agitators 604 drive the three unblocking gears 605 to rotate on the drive gear ring 606, thereby driving the three rotating agitators 604 to rotate synchronously, unblocking the titanium dioxide in the intermediate feed pipes 601, and avoiding the problem of feeding failure or feeding agglomeration due to titanium dioxide agglomeration.

[0068] Furthermore, when titanium dioxide falls onto the feed transfer plate 709, if the titanium dioxide is too wet, it will stick to the feed transfer plate 709, causing the feed transfer plate 709 to move downwards and drive the feed puller 708 to move. The feed puller 708 moves vertically downwards in the pull groove 721, causing the pull spring 722 to be stretched. When the feed puller 708 moves, it moves through the drive sliding shaft 714 in the drive sliding hole 713, thereby driving the sliding push plate 712 to slide horizontally. The sliding push plate 712 pushes the slide plate horizontally. The outer pull rod 705 rotates on the reset shaft 706, which in turn drives the reset torsion spring 720 to bear force. When the outer pull rod 705 rotates, it pushes the outer pull frame 704 to move through the rotating push shaft 707. This causes the outer pull frame 704 to move the outer pull cutting plate 702. The outer pull cutting plate 702 slides in the outer pull groove 701, which blocks the transfer feed pipe 601, preventing a large amount of wet material from falling into the vibrating screen cylinder 1 and causing damage to the screen inside.

[0069] Furthermore, it should be further explained that when the external pull-out plate 702 moves, it squeezes the four positioning spring rods 716 to retract simultaneously, causing the positioning spring rods 716 to move within the positioning spring grooves 715 and drive the positioning springs 718 to contract under force. When the external pull-out plate 702 moves to the designated position, under the rebound force of the positioning springs 718, it drives the positioning spring rods 716 to lock into the corresponding positioning slots 717, so that the position of the external pull-out plate 702 can be fixed, realizing the automatic material cutting function. In addition, if the screen in the vibrating screen cylinder 1 is damaged, causing a large amount of material to be discharged from the discharge pipe 2, titanium dioxide will also accumulate rapidly on the discharge transfer plate 711 at the corresponding position, which will then cause the discharge transfer plate 711 to drive the discharge pull-down bracket 710 to move. The discharge pull-down bracket 710 will drive the feeding pull-down bracket 708 to move, thereby achieving the purpose of emergency material cutting.

[0070] Furthermore, when the vibrating screen cylinder 1 vibrates abnormally, it causes the vibrating screen cylinder 1 to press down the driving frame 1104 and move. The driving frame 1104 moves vertically within the pressing groove 1105, causing the support spring 1106 to contract under force. When the driving frame 1104 moves, it simultaneously drives the wedge-shaped separation block 1103. The wedge-shaped separation block 1103 presses the centralized separation plate 1101 and moves it. The centralized separation plate 1101 slides on one side of the control box 8 through the limiting pull rod 1102, thereby causing the centralized separation plate 1101 to simultaneously drive the three plugs 10 to separate from the control box 8, thus achieving the purpose of active separation and avoiding the problem that the vibrating screen cylinder 1 will continue to vibrate during excessive vibration, causing further damage to the vibrating screen cylinder 1.
